duplex (Management
Ethernet)

To configure duplex
mode operation on a Management Ethernet interface, use the
duplex command
in interface configuration mode. To return the interface to autonegotiated
duplex mode, use the
no form of the
duplex command.

duplex
{ full | half }

noduplex

Syntax Description

full

Configures
the Management Ethernet interface to operate in full duplex mode.

Command Default

Autonegotiates
duplex operation

Usage Guidelines

To use this command, you must
be in a user group associated with a task group that includes appropriate task
IDs. If the user group assignment is preventing you from using a command,
contact your AAA administrator for assistance.

mac-address
(Management Ethernet)

To set the MAC layer
address of a Management Ethernet interface, use the
mac-address
command in interface configuration mode. To return the interface to its default
MAC address, use the
no form of the
mac-address
command.

mac-addressvalue1.value2.value3

nomac-address

Syntax Description

value1

High 2 bytes
of the MAC address in hexadecimal. Range is from 0 to ffff.

value2

Middle 2
bytes of the MAC address in hexadecimal. Range is from 0 to ffff.

value3

Low 2 bytes
of the MAC address in hexadecimal. Range is from 0 to ffff.

Command Default

The default MAC
address is read from the hardware burned-in address (BIA).

speed (Management
Ethernet)

To configure the
speed for a Management Ethernet interface, enter the
speed command
in interface configuration mode. To return the system to autonegotiate speed,
use the
no form of the
speed command.

speed
{ 10 | 100 | 1000 }

nospeed

Syntax Description

10

Configures
the interface to transmit at 10 Mbps.

100

Configures
the interface to transmit at 100 Mbps.

1000

Configures
the interface to transmit at 1000 Mbps (1 Gbps).

Command Default

Interface speed is
autonegotiated.

Command Modes

Release

Modification

Release 3.7.2

This command
was introduced.

Usage Guidelines

Note

Keep in mind that
both ends of a link must have the same interface speed. A manually configured
interface speed overrides any autonegotiated speed, which can prevent a link
from coming up if the configured interface speed at one end of a link is
different from the interface speed on the other end.

Table 1 describes the performance of the system
for different combinations of the duplex and speed modes. The specified
duplex command
configured with the specified
speed command
produces the resulting system action.
